/**************************************************************** GestureTest.ino APDS-9960 RGB and Gesture Sensor Shawn Hymel @ SparkFun Electronics May 30, 2014 https://github.com/sparkfun/APDS-9960_RGB_and_Gesture_Sensor Tests the gesture sensing abilities of the APDS-9960. Configures APDS-9960 over I2C and waits for gesture events. Calculates the direction of the swipe (up, down, left, right) and displays it on a serial console. To perform a NEAR gesture, hold your hand far above the sensor and move it close to the sensor (within 2 inches). Hold your hand there for at least 1 second and move it away. To perform a FAR gesture, hold your hand within 2 inches of the sensor for at least 1 second and then move it above (out of range) of the sensor. Hardware Connections: IMPORTANT: The APDS-9960 can only accept 3.3V!
